The Hufeisensiedlung is a housing estate in Berlin, built in 1925-33. It enjoys international renown as a milestone of modern urban housing. It was designed by architect Bruno Taut, municipal planning head and co-architect Martin Wagner, garden architect Leberecht Migge and Neukölln gardens director Ottokar Wagler. In 1986 the ensemble was placed under German heritage protection. On July 7, 2008, it was awarded UNESCO World Heritage status as one out of six Berlin Modernism Housing Estates. Since 2010, the Horseshoe Estate has also been listed as a garden monument. The Hufeisensiedlung is probably the most outstanding example of innovative German town planning during the 1920s.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
